Analysis of dynamic effects in micro milling process

Abstract

Micro milling is the most flexible and fastest way to machine miniature structures prepared of different kind of materials. This method is actually the transportation of conventional sized milling into the range of 0-999 microns. Micro milling is characterized by relative large dynamic effects, which have impacts on the machining quality and accuracy. Main aim of this research work is mapping and understanding of these effects, and hence the active increasing the stability of the process. Systematic series of experiments were carried out in order to analyse the cutting forces and vibrations. Dominant frequencies were determined, and phenomenon of chatter was investigated.
